您如何以编程方式启动用户选择的Daydream? [英] How do you start the user's selected Daydream programmatically?

问题描述

在我的Galaxy Nexus上，我可以在系统偏好设置中点击此按钮以开始我当前选择的白日梦.

On my Galaxy Nexus, I can tap this button in system preferences to start my currently selected daydream.

是否可以通过Intent在应用程序中重现此功能?我没有白日梦服务，但我想允许用户开始他们喜欢的白日梦.

Is there a way to reproduce this functionality in an app via Intent? I don't have a daydream service, but I would like to allow the user to start their preferred daydream.

推荐答案

• 编辑9/22/2014:这在某些三星手机上不起作用 我通过挖掘一些Android源代码来弄清楚如何做到这一点.
• Edit 9/22/2014: This does not work on some Samsung phones I figured out how to do this by digging through some Android source code.

final Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName("com.android.systemui", "com.android.systemui.Somnambulator");
startActivity(intent);

此处提供示例应用.
